Solubility In Water

Water is considered a polar molecule because:

The uneven distribution of charge

When salt (NaCI) dissolves in water, what happens to the ionic bonds?

They are broken by water molecules

The process where solvents and solutes interact through attractive forces is called

Solvation

In an aqueous solution what is the solvent?

Water

The substance being dissolved

Solute

Attraction between an ion and a polar molecule

Ion-dipole force

The substance that does the dissolving

Solvent

A solid that forms when a substance is insoluable

precipitate

The process of molecules surrounding solute particles

Solvation

What happens when ionic compounds is added to water

the polar water molecules surround the positive ions, breaking the ionic bonds that hold the crystal together

The ions become surrounded by water molecules and move

Freely forming a homo solution

What happens when a polar covalent compound like sugar is added to water?

The water molecules form hydrogen bonds with the molecules of the solute, dispersing them through the water

In a polar covalent compound, what happens to the molecules?

The molecules dont break into ion, but they become solvated by the water

What happens when a substance is insoluble?

The forces holding its particles together are too strong for the water molecules to overcome, so the substance remains a solid and settles out of the water, forming a precipitate

Solvents and solutes interact through forces like

Ion-dipole, dipole-dipole, and LDFS through solvation

What are electrolytes?

Substances that dissociate into ions

What are electrolytes in living things?

They are minerals that carry an electric charge, such as sodium, potassium, calcium, and magnesium

What are the minerals in your body important for?

Regulating fluid balance, supporting nerve and muscle function, and maintaining your body’s PH balance

What happens to the ionic bonds in the salt crystal during dissoluton?

The ionic bonds in the salt crystal break due to the water molecules surrounding the + and - ions

What is dissolution?

the process where substances (solutes like salts, sugars, or drugs) break down and disperse into a liquid
